Place students in teams of three. Students discuss and collaborate together in their teams abut each coral reef threat on the worksheet. Together they come to an agreement as to whether the threat is man made or natural. To conclude the activity each team presents their opinions to the class about one of the coral threats. Use these questions to guide their presentations. - 1. What the threat is?,
2. What is causing it?, 3. Are there potential solutions or actions that can be taken to minimise or stop the problem?
